The 2003 Geotechnical News paper Case Study: Thermal Analysis of Artificial Ground Freezing at the McArthur River Uranium Mine describes a case study of the engineering carried out to artificially freeze the underground ore body at the mine prior to mining. Freezing was necessary to deal with rubble, flowing sand, clay, and high water pressures around the ore body located about 550 meters below ground level. The computer code TEMP/W was used to model the freezing of the ground and to establish heat losses from the soil. During actual field freezing operations, thermocouple strings were monitored to quantify temperature decay. Comparison of predicted and monitored temperatures was excellent.
